REVERSIBLE TURBINE.

SPECIFICATION forming part of Letters Patent No. 758,595, dated April26, 1904.

Original application filed December 6, 1902, Serial No. 134,208. Dividedand this application filed November 27, 1903. Serial T0 at wlemw itmayconvern:

Be it known that I, CHARLES FERDINAND DE KIERzKowsKI-STEUART, a subjectof the King of Great Britain, and a resident of St. Stephens Club,Westminster, in the city of London, England, have invented certain newand useful Improvements Relating to Reversible Turbines, of which thefollowing is a specification.

Turbine-wheels which are driven by a jet or jets of steam or othermotive fluid are usually capable of rotation in one direction only.

The present invention, which has been described in application SerialNo.-134,208, filed December 6, 1902, of which the present application isa division, has reference to an arrangement by means of which aturbinewheel may be made reversible. To this end I provide asymmetrically-constructed turbine-wheelr that is to say, one which canbe equally-well acted on either wayand a deflecting device by which thejet or jets may be pointed in either direction.

In the accompanying drawings, Figure 1 shows in plan view aturbine-engine embodying my invention, the cover of the wheel-casingbeing removed. Fig. 2 is a section on the line A B of Fig. 1, and Fig. 3is a sectional plan illustrating the deflecting device.

s is the wheel-casing, and t is the wheel mounted therein. This wheel ispreferably of the construction shown in the drawings, in which case itconsists of an outer cylindrical shell Q0, which may be wound round withwire of high tensile strength and is mounted on the engine-driving shaft0. -An annular frame a, fitting into the frame w, forms an annular (Nomodel.)

through channel or passage. passage 24 is intersected by a large numberof fine wires 00, closely spaced. Immediately opposite the jets, wherethey enter the wheelcasing, are arranged deflectors y, which are capableof being shifted, as shown in Figs. 1, 2, and 3. The deflectors y areintended to guide the jets at a suitable angle into the annularwire-intersected passage of the turbinewheel, through which the Workingfluid passes in a helical course to the exhaust-passage 2, leading to acondenser or the outer air.

The movable deflectorsare arranged in oppositely-inclined pairs (seeFig. 3) in a double ring 1, capable of sufficient rotary movement tobring one or other set of deflectors to act upon and divert the incomingjets in one direction or the other. Rotary movement is given to the ring1 by means of an eccentric 2 and link 3. (See Fig. 2.)

What I claim as my invention, and desire to secure by Letters Patent,is-- In a turbine-engine the combination with a deflecting device forthe jet and means for moving said device to point the jet in eitherdirection, of a reversible turbine-wheel comprising an inner and outershell and an annular channel closely spaced with intersecting wires,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES FERDINAND DE KIERZKOWSKI-STEUART.
